The mystery "man in white" has led Belgian authorities astray and he has wrongly been identified twice.

Conflicting reports into the identity of the three men who blew up Zaventem Airport on Tuesday morning has sparked criticism and concern of how the Belgian authorities are handling the aftermath of the massacre.

Prosecutors today said a man had been charged but did not confirm whether he was the man pictured walking through the departure lounge with a suitcase jampacked with nails and explosives.

Belgian media, however, are reporting the third airport bomber is Chaffou.
